IMPRovEMEN'r IN BolLER-CLEANERS.

Specification forming part of Letters Patent No. 192,741, dated July 3, 1877; application filed May 23, 1877.

To all whom it may concern Be it known that I, TnoMAs OEANEY, of Bay City, in the county of Bay and State of Michigan, have invented an Improvement in Mud-Extractors, of which the following is a specification V The nature of my invention relates to an improvement in mud-extracting attachments to steam-boilers of that class wherein the separation of the foreign matters is effected by circulating the water through'depositingh chambers; and the object I have in view is to eliminate the heavier insoluble impurities from the water, as well as the lighter earthy and vegetable impurities held in suspension.

To this end my invention consists in combining with the circulating-pipe and elevated settling-chamber heretofore used a catchplate and siphon, connected with the rising leg of the circulatingpipe, the said plate being so arranged in the boiler as to cause a rapid circulation of the water to and over its surface, upon which the heavier impurities will deposit, to be removed by the siphon-cir culator into the elevated tank.

Figure l is a perspective view ot the dev vices as applied to a steam-boiler, a portion of which is shown. Fig. 2 is a longitudinal vertical section at a: x. Fig. Sis a cross-section at y y.

In the drawing, A represents a portion of the shell of a steam-boiler, of which B B are iiues.

C is a pipe, rising from a point below the Water-line in the boiler through the top ot' its` shell, and into an elevated tank, D, from which the return-leg E extends toward the rear end of the boiler, passing down into the same, and terminating in an upturned discharge-bend, E', below the water-line. The end E' is turned up to avoid opposingthe upward currents of the water in the boiler.

On the ues is laid a large basin-shaped circulating-plate, F, with an opening in the middle, in W-hichis fitted an inverted Siphon, G, at the bottom of the rising leg C, above whichfthere isa Tee, into which a pendent elbow, Cl, is tapped, which terminates in bellmouth deiectors C2.

As steam is generated there is an upward rushof water, which flows over the plate F' to its middle; thence up through the ascending leg C into the elevated tank, which, being cooler than the boiler, lowersthe temperature of the water, causing the precipitation of the particles held in suspension, the clear water returning tothe boiler through the pipes E E. The vegetable matters and lighter earthy impurities held in suspension oat on the surface of the water, and are drawn toward and into the bell-mouth detlectors (l2, thence through the elbow (P into the leg C, whereupon the said impurities are eliminated, as described, and in the manner already well known.

But the heavier impurities, which would ordinarily settle and deposit as scale, are not to be removed in the above-described manner; and in the present case they are deposited ou the plate F, and carried by the currents to the mouth ofthe inverted siphou G, whence they are taken up through the as-- cending leg and deposited in the elevated tank, whence they are removed by occasionally blowing oi' at the bottom through cock H.

1t will be-noticed that the pendent elbow O1 is funnel-shaped where'it passes through the connecting-plate of the deieotors O2, which facilitates the upward iow of the water, and that said Vdeieetors are open below, in con tradistinctiou to the trumpetmouths heretofore used in devices of this class for gathering the iloating impurities.

What I claim as my invention is- 1. The combination, with a steam-boiler, of the large pan-shaped catch-plate F, and the inverted siphon G, opening upwardly through the said catch-plate, for conducting off the heavy particles deposited on such plate, constructed and arranged substantially as described and shown.

2. The flaring elbow C1, deflectors G2, and catch-plate F, in combination with the ascending leg of a water-circulating mud-extractor, substantially as and for the purpose set forth.

3. The combination, with the pipe U, of the downwardly-turned deilectors G2, for conducting oft' the surface-Water, the catch-plate F, below such deilectors, and the inverted Siphon G, for conveying oi' the heavy particles not taken up by the said deectors and deposited on the said plate, substantially as described and shown.
